Description

BIKEWAY USING LONGITUDINAL GIRDER WITH DIFFERENT HEIGHT AND PILE AND CONSTRUCTION METHOD THEREFOR}

The present invention relates to a bicycle road and a construction method using a mold different from the pile and the cross-sectional height. More specifically, in forming additional bicycle roads for smooth passage of bicycles or pedestrians on the side of roads or sidewalks, bicycle roads using molds with different cross sections and heights to support the bicycle roads more stably and It is about the construction method.

Recently, many bicycle roads have been constructed in accordance with the green growth policy, such as the bicycle path creation project that is being implemented to allow people to ride safely while being in harmony with the beautiful surroundings as an eco-friendly leisure space that many people can enjoy comfortably. There is a situation.

Figure 1a shows a construction example of the bicycle road by the cantilever construction method by the conventional anchor fixing.

That is, in the bridge upper structure (S) provided with the curb 20 in the longitudinal direction at both ends in the width direction of the bridge top plate 10, a plurality of bolts 80 and nuts 81 to the curb 20 To form a fixing bracket 30 is fixedly installed,

On one side of the fixing bracket 30 is installed an expansion bracket 40 fixed to the bolt 80 and the nut 81,

Between the expansion bracket 40 is provided with a longitudinal member 50 which is installed a plurality of welding in the longitudinal direction of the bridge,

The upper surface of the handrail 60 and the expansion bracket 40 and the longitudinal member 50, which are fixed to a plurality of bolts 80 and nuts 81 on the side of the other end of the expansion bracket 40, It can be seen that the construction of the expansion portion (70, bottom plate) made of a plurality of lightweight wood arranged in the axial direction to follow.

That is, the expansion portion (bottom plate) can be a kind of bridge slab that can be passed by a bicycle or a person, because it is to be installed hanging on one side of the existing bridge of the bracket 30 and a beam form of the angle member The expansion bracket 40 was bound to follow the method of connecting the bolt 80 and the nut 81 to the outer surface (curbstone) of the existing bridge.

Accordingly, when the bicycle passes, all the loads are concentrated on the connection portion of the fixing bracket 30 and the curbstone 20 and the expansion bracket 40 in the form of a beam. Due to the large burden on the connection portion was forced to install the expansion portion 70 in a lightweight material.

In FIG. 1a, it can be seen that an extension part 70 (wood deck) made of light wood is used.

An example of a conventional road or bridge for solving this problem can be seen in Figure 1b. In other words, it can be said that a bicycle road is constructed by using piles on the side of the road.

That is, according to Figure 1b

A ready-made concrete pile 81 driven in the ground;

A steel coping bracket 82 installed to cover the top of the ready-made pile 81;

A fastening member 83 disposed to face the steel coping bracket 82 so as to be fixed to the ready-made pile 81 and integrally connected to the pillar pile 81 by a frictional force;

A mold 84 having a plurality of H beams fixed to the upper surface of the steel coping bracket 82 by high tension bolts; A bottom plate 85 installed on an upper surface of the mold 84 and made of a concrete panel or a wood deck;

It can be seen that the bridge for the bicycle sidewalk consisting of handrails 86 fixedly installed at fixed heights and steps on both sides of the mold 84.

Therefore, the bottom plate 85 is supported by the ready-made pile 81 and the steel coping bracket 82 so that the bottom plate 85 can be resistant to a larger working load so that the bottom plate 85 can be weighted. It is.

However, the ready-made pile 81 is installed on the side surface of the road, such as the construction conditions of the bicycle road, since the workability is reduced, it is necessary to reduce the number of installation of the ready-made pile if possible.

Therefore, the construction by installing and supporting one ready-made pile 81 at the center bottom of the steel coping bracket 82, the steel coping bracket is installed on the ready-made pile 81 when the transverse width of the bottom plate is increased ( The transverse width of 82) should also be large. In this case, there was no limit to securing structural stability of the steel coping bracket 82.

In other words, the steel coping bracket 82 is also installed as a cantilever on both sides of the pillar rather than a stable structure by supporting both ends. .

First of all, when constructing a bicycle road using the ready-made pile according to FIG. 1B, a plurality of ready-made piles 81 should be spaced apart from each other in the longitudinal direction of the road, and a plurality of molds (84) may be provided depending on the width of the bottom plate. ) Also had to be installed in the transverse direction, which has the disadvantage of increasing the actual cost of construction.

Also, as shown in FIG. 1C, the coping portion of the piers is laterally expanded without installing the ready-made pile 81, and a vertical pillar member 91 is installed on the expanded coping portion A, and the upper surface of the vertical pillar member 91 is formed. After installing the mold 92 in the expansion bracket 93 and the fixing bracket 94, an example of installing the bottom plate has also been introduced.

However, in order to construct the expanded coping part A, when the temporary facility and additional concrete is poured, or when the coping part is formed of steel, when the jointing method such as an anchor is applied to the connection with the existing concrete piers, the joint performance is deteriorated. Since the bottom plate load acts as an additional load on the pier, there is a problem such as deterioration of safety of the existing pier coping part, which inevitably degrades the constructability and economic efficiency.

Therefore, the present invention is to bias the load sharing on the pile installed on the side of the bridge in the road for the bicycle to be installed so that the passage of the bicycle or pedestrians smoothly, but to share the less load on the fixing bracket, the installation of the mold Provides a bicycle road and its construction method using molds with different profile heights and cross sections, which can be more efficiently loaded and can be economically constructed, and can be installed economically by greatly reducing the number and widening the pile separation distance in the longitudinal direction. It is a technical problem.

The present invention

First, the fixing bracket is installed on the outer side of the bridge, and the pile (PILE), such as a steel pipe spaced laterally, is installed.

Accordingly, the bracket molds having the small cross-sectional height are spaced apart from each other in the longitudinal direction on the upper surface of the fixing bracket, and the molds for the pile having the large cross-sectional height are continuously installed in the longitudinal direction on the upper surface of the pile.

That is, when the magnitude of the load transmitted to the fixing bracket increases, the phenomenon that the fixing bracket falls off from the outer surface of the bridge occurs, which causes the collapse of the bicycle road.

Accordingly, a small load is distributed to the fixing bracket, and the mold installed on the upper surface of the pile is biased toward the pile by using a large cross-sectional height.

When using molds with different cross-section heights, the load on the pile increases, but this can be shared by using the supporting force of the pile, and the safety of the fixing bracket can be secured, thereby reducing the risk of a safety accident.

Secondly, the mold installed on the fixing bracket and the mold installed on the upper surface of the mold are connected to each other by using an upper horizontal beam, but the upper horizontal beam is installed to be spaced apart from each other in the longitudinal direction at a predetermined interval.

The upper horizontal beam spaced apart from each other at a predetermined interval by the relatively economical channel (type) by installing a member to ensure economic feasibility, while the deck is supported on the upper surface of the channel member stably.

That is, the flooring material is to be supported on both the upper surface of the bridge, the mold for the bracket having a small cross-sectional height, the mold for the pile with a large cross-sectional height, and the upper surface of the channel member so that the load of the flooring is distributed.

Third, since the load transmitted to the pile is increased, the pile is connected to the lower side of the piers by using the lower horizontal beam to secure the pile.

To this end,

Files installed on the shift and pier sides of the bridge;

A fixing bracket fixedly spaced apart in the longitudinal direction on the upper surface of the bridge;

A lower horizontal beam installed transversely between the pile and the alternating and piers to connect the pile and the bridge to each other;

A mold for a bracket installed to be supported by the fixing bracket and spaced apart from each other in the longitudinal direction;

A mold for a pile supported by the pile and installed continuously in the longitudinal direction;

An upper horizontal beam connecting the mold for the bracket and the mold for the file in a transverse direction;

A channel member extending in the longitudinal direction on the upper horizontal beam upper surface;

Deck extending in the longitudinal direction on the upper surface of the channel member; including the cross-sectional height (h2) of the mold for the pile is formed to be larger than the cross-sectional height (h1) of the mold for the bracket,
One end of the deck extends to the upper portion of the bridge outer surface and the other end is provided to the bicycle road and the construction method using a mold having a different cross-section height and installed to extend to the upper surface of the mold for the pile.

The scope of the present invention is shown by the following claims rather than the above description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

The bicycle road according to the present invention is a bicycle road using a mold with a different pile and a safe pile without structural defects supporting most of the extension load by making safety prevention a priority but more economical construction. The construction method can be provided.

In addition, it is possible to construct a more economic bicycle road by eliminating the construction of the bicycle road by the unnecessary many H-shaped bracket for expansion.

[Bicycle Road Using Mold with Different File and Section Height (100)]

Figure 2a is a partial perspective view of the bicycle road of the present invention, Figure 2b is an overall construction of the bicycle road.

The bicycle road 100 is a pile 110, a fixing bracket 120, a lower horizontal beam 130, a mold for a bracket 140, a mold for a pile 150, an upper horizontal beam 160, a channel member ( 170, and deck 180.

Looking at the basis of Figures 2a and 2b,

The pile 110 may be used by a steel pipe which is spaced apart in the longitudinal direction at the side of the bridge 200, that is, the position spaced laterally.

The pile 110 is installed to be located on the side of the bridge 210 and the bridge 220, which is a lower structure of the bridge 200, as shown in Figure 2b, so the pile 110 is not located in the center of the bridge span It can be seen that it does not interfere with the cross section.

The pile 110 is constructed by using a non-shown ride, etc., but the upper surface of the pile 110 is installed to support the mold 150 for the pile to be described later after the head 111 is installed.

The fixing bracket 120 is a member that is installed on the upper side (curbstone, etc.) of the bridge to support the mold for the bracket 140 to be described later.

The fixing bracket 120 is disposed so as to span the upper surface (curbstone, etc.) of the bridge to be fixed by the anchor bolt and the fastening nut, so if a large load is supported, safety problems may occur.

Accordingly, the upper plate 121 is placed on the upper surface of the upper portion of the bridge (kerbstone, etc.) so that the vertical plate 122 is fixed to the outer surface of the upper portion of the bridge (kerbstone, etc.) by anchor bolts and fastening nuts. The 123 is installed to protrude laterally under the vertical plate 122 so that the bracket mold 140 is installed on the upper surface of the horizontal support jaw 123.

It can be seen that the fixing bracket 120 is installed to be spaced apart in the longitudinal direction on the outer surface (curbstone, etc.) as shown in Figure 2b.

At this time, the lower horizontal beam 130 is installed between the sides of the pile 110 and the alternating 210 and the pier 220, the lower horizontal beam 130 may use an H-beam or the like.

The lower horizontal beam 130 serves to constrain the pile 110 by being connected to the alternating 210 and the piers 220. It can support the horizontal load acting, restrain the collapse of the pile 110 when the deck 180 to be described later to fall to play an important role in ensuring the safety of the bicycle road.

One end of the lower horizontal beam 130 is fixed to the anchor bolt and the fastening nut by using an overlay plate on the side of the alternate 210 and piers 220, the other end using a connecting plate on the outer surface of the pile 110 The connection bolt and the fastening nut are used for the connection.

The bracket mold 140 is to use the H-shaped steel. The bracket mold 140 has a bottom surface supported by the horizontal support jaw 123 constituting the fixing bracket, and forms a cross-sectional height h1 to match the upper surface of the fixing bracket 120.

Accordingly, the bracket mold 140 may be fixed to each other by a connection bolt and a fastening nut to the horizontal support jaw 123 constituting the fixing bracket.

In this case, as shown in FIG. 2B, the mold for the bracket 140 is installed between the fixing brackets 120, but it is not installed between all the fixing brackets 120, but may be installed to be spaced apart by a predetermined interval.

As such, the reason for installing the bracket mold 140 is to reduce the number of installation of the bracket mold 140 and to secure economical efficiency, while reducing the number of installations so that the load is not concentrated by the bracket mold 140 and thus the fixing bracket 120 This is to reduce the load transmitted to).

The pile mold 150 is installed in the longitudinal direction so that the bottom surface is supported on the support plate of the upper surface of the pile 110, the upper surface is arranged to have the same height as the upper surface of the bracket-type mold 140, but the cross-sectional height (h2) Is larger than the cross-sectional height h1 of the bracket type mold.

Thus, the difference between the cross-sectional height of the bracket-type mold 140 and the pile mold 150 is that the longitudinal bending stiffness becomes very large as the cross-sectional height increases, so that the mold for the pile due to the difference in bending rigidity of the two molds ( It is to reduce the load transmitted to the fixing bracket 120 by increasing the load sharing ratio of 150).

Also, as shown in FIG. 2B, the mold 150 for the pile may be installed to extend continuously in the longitudinal direction to the upper end of the pile 110 and the adjacent pile. Such a mold for the pile 150 may have a long span, but increase structural cross-sectional efficiency. In order to pre-stress is introduced by placing the tension member not shown in the longitudinal direction in the bottom of the mold.

In addition, since the handrail is installed on the upper surface of the mold 150 for the pile, the load is increased so that the handrail load is biased to the mold 150 and the pile 110 for the bracket. A difference is made in the cross-sectional height of the mold 150.

The mold 150 for the pile is installed to be continuous in the longitudinal direction, and if there is a limit to the extension length is to be installed continuously using an additional plate.

The upper horizontal beam 160 supports the channel member 170 and the deck 180 which will be described later by connecting the bracket mold 140 and the pile mold 150 to each other.

The upper horizontal beam 160 can also use the H-beam like the lower horizontal beam 130, one end is connected to the abdominal connecting plate installed on the abdomen of the bracket for the mold 140 by the connecting bolt and the fastening nut, the other end It is to be connected to the abdominal connecting plate of the mold 150 for the pile by a connecting bolt and a fastening nut.

The upper horizontal beam 160 may be installed for each site where the fixing bracket 120 is installed.

The channel member 170 is to use a magnetic channel member, unlike the prior art by not using the H-shaped steel to ensure the installation and economical efficiency.

That is, the channel member 170 is installed to extend continuously in the longitudinal direction in order to transfer the load of the deck 180 to the upper horizontal beam, in which case the number of uses increases to use the H-shaped steel very uneconomically do.

Accordingly, the present invention uses a relatively light, easy to install and economical channel member and is installed to extend continuously in the longitudinal direction, and to be spaced apart from each other in the transverse direction.

The deck 180 is a bottom plate is to use a deck of light wood or lightweight material. The deck 180 is subjected to a load of a bicycle or a pedestrian is to expand the support structure to enable a more secure installation.

Accordingly, one end of the deck 180 is extended to the upper side of the bridge outer surface 124 and the other end is extended to the upper surface of the mold 150 for the pile to ensure a more secure support state.

Thus, it can be seen that the height of the upper surface of the mold for the bracket and the file mold and the upper surface of the channel member are positioned on the same horizontal surface to ensure flatness of the deck, and are constructed according to the height of the upper surface of the pile accordingly.

[Construction method of bicycle road (100) using mold with different file height and cross section]

3a to 3c illustrate the construction method of the bicycle road 100 using a mold having a different cross section height from the pile in order.

First, as shown in FIG. 3a, the fixing bracket 120 is installed on the upper outer surface (curbstone) of the bridges and bridges 210 and 220 of the existing bridge 200 by using the connecting bolt and the fastening nut.

It is fixed to the anchor bolt and the fastening nut by using the attachment plate 131 for fixing the lower horizontal beam 130 to the outer surface of the alternating and piers (210, 220) of the lower fixing bracket 120.

At this time, the fixing bracket 120 is spaced apart from each other in the longitudinal direction so that a plurality are installed, the back plate 131 is also installed in the shift and piers.

Next, as shown in FIG. 3B, the pile 110 is installed at a position spaced apart laterally from the alternating and pier 210 and 220 of the bridge 200.

The pile 110 may be installed to be spaced apart from each other in the longitudinal direction only on the sides of the alternating and piers 210 and 220.

A support plate is formed on the upper surface of the pile 110 to allow stable support of the mold for the pile, and the support plate 111 may be installed on the upper surface of the pile to have a supporting function of the mold for the pile. have.

When the construction of the pile 110 is completed, the pile 110 is installed by installing the lower horizontal beam 130 using the connecting bolt and the fastening nut to the connecting plate installed on the outer circumferential plate 131 and the pile 110 installed earlier. To be bound by the bridge's turns and piers.

Next, as shown in FIG. 3C, the bracket mold 140 and the pile mold 150 are installed on the fixing bracket 120 and the pile 110, respectively.

At this time, the bracket mold 140 is installed in the longitudinal direction, but it can be seen that the installation is spaced apart at regular intervals without being installed to span the entire fixing bracket 120,

It can be seen that the mold 150 for the pile is installed to extend in the longitudinal direction.

If the extension length of the mold 150 for the pile is limited, it is possible to ensure more efficient bending stiffness by connecting to each other by using a back plate and the like continuous.

Next, when the bracket mold and the file mold are respectively installed, the upper horizontal beam 160 to connect them to each other is installed.

The upper horizontal beam 160 is to be connected between the abdomen of the mold for the bracket and the abdomen for the pile using the abdominal connecting plate, the connection bolt and the fastening nut.

Next, the channel member 170 is installed as shown in FIG. 3d, but is installed to be continuous in the longitudinal direction, but installed to be supported by the upper horizontal beam.

The deck 180 is installed on the upper surface of the channel member 170. The deck 180 has one end supported by the upper portion 124 of the bridge outer surface, and the other end is supported by the upper mold surface for the pile.

Furthermore, the railing 300 is installed on the upper surface of the pile mold 150 so that the construction of the bicycle road can be completed.
